Hey Kirk -- None of those files are on the Compact Flash cards, just an empty miscellaneous folder as with all canons and the DCIM folder with the 100EOS1D folder with standard images inside. And I have reformatted very often, so its doubtful any hidden files could cause this constantly.
Also, I'm ingesting with a Lexar CF/Expressport reader and writing to an SSD drive, in case that's important.
